Thanks.
I contacted one of my favourite LFS (Fishworld in Keysborough Vic) & they put me onto Lee at Australian Aquariums in Carrum Downs. Lee can do it for about a hundred which is very reasonable think. We're taking it down tomorrow.
Looks like part of the kids' school fees are going to have to wait. The upside is that with the tank gone and the stand open at the top, I can tidy everything up in there, label it, drill ready for fans etc to go in later. There was no way Donna (my wife) was going to let me quit this far in.
